Syncing school e-mail with Pre

I need some assistance figuring out if I can sync my student e-mail address at Towson with my Pre (as the primary e-mail that automatically updates etc etc..). The e-mail address is powered by gmail, but actually appears as something like: student1@students.towson.edu. I can get it to recognize the e-mail address, but it doesn't sync my inbox, contacts or anything. Can anyone please walk me through this??
